How to use this deck

Getting Cerberus to your starting hand

Use either Sorcery Conduit or Draw Sense: Low Level to get Cerberus early in the duels. If you get Abyssal Designator in your starting hand, or any other cards that can reduce your LP, it's recommended to use 1 in first turn since Tea occasionally does not summon a monster that can deal 1800 damage. Using Abyssal ensures you can draw it next turn, but make sure you don't choose a card that she can discard so she doesn't lower the number of cards in her deck. Set an Enchanted Javelin only if you know you will use it, otherwise it will just take up space and Cerberus' total attack will not go over 10,000.

Buffing up the Cerberus

Once Cerberus is summoned, use the spells that you have in your hand so that the attack is about 2400. This is so that Tea can't destroy your Cerberus with Dunames or Dark Magician Girl. Keep using the spell cards and pass the turns until you are left with 0 cards in your deck, but don't equip him with all 3 spell cards since you need 1 slot open to use some spell cards. Use Murmur of the Forest after you put the Yami field spell so that you can return it back and re-use it. Once you are out of cards in your deck, equip him with the Shooting Star Bow - Ceal to attack directly.

Draw cards faster

Shard and Jar of Greed

Be sure to use and activate Shard or Jar of Greed the moment you get them, since Tea has cards like Skelengel and Cards from the Sky that allows her to draw faster, and you don't want her to run out of cards before you do. You will also want to be able to draw some Twister early so that she doesn't keep healing from Solemn Wishes.

Twister

The Twisters are needed to get rid of her Solemn Wishes so she doesn't get over 10,000 LP. If she does not end up using Solemn Wishes, you can use Twister on your own cards if you enable self-chain from the in game settings.

Thanks for this advice - it worked perfectly for me on my first ever farm.

I don't have twisters either, you don't really need them, the only purpose they serve is to stop her 2 lifepoint traps. You can use Remove Trap to get rid of 1 of them, which is usually enough. You can get it from a Duel School mission.

LuckiestPersonEver

I'd been trying to get a deck close to this as I neared stage 30. Anyways, I just hit 30 and unlocked the level 40 duelists, and decided to try it out when I saw level 40 Tea in duel world. First time doing a level 40 and this happened....

Just wanted to say that I've just spent 800+ blue keys on her with this deck (actually I modified a bit to give me 7000~8000). The reason? I need a f***ing Dark Magician girl to beat mission 48. (I know we get one from Tea after unlocking her. But at the time I was a nocive and I sold it right away for a UR gem).
Unfortunally I couldnt get a single one >:(
Does anyone knows if that card probability is more rare to appear than the other cards on her "lvl 40 prize cards"? :(
